We develop a simple model of digital markets to analyze the impact of Covid- 19 on the digital transformation of sectors. The lockdown due to Covid-19 is modeled as a shock that wipes out the physical market, temporarily leaving digital consumption as the only option. Under plausible assumptions on digital demand and supply, the model predicts that such temporary shock produces an irreversible rise of the digital markets. This happens for three distinct reasons. First, by temporarily eliminating the physical market, Covid-19 provides a strong incentive for rms to carry out the xed investments necessary to venture into the digital market (supply channel). Secondly, by forcing even the most reluctant consumers into the digital market, Covid-19 pushes them to familiarize with digital platforms, and this con dence endures in the post-Covid era (demand channel). Finally, if consumerstaste for digitalization is a¤ected by the size of the digital market, a market may be entrapped into a low-digital equilibrium inde nitely. In such context, the lockdown due to the pandemic is the shock that may unleash the forces of digitalization and tilt the entire sector towards a high-digital equilibrium (network externalities channel)

Abstract
We develop a simple model of digital markets to analyze the impact of Covid- 19 on the digital transformation of sectors. The lockdown due to Covid-19 is modeled as a shock that wipes out the physical market, temporarily leaving digital consumption as the only option. Under plausible assumptions on digital demand and supply, the model predicts that such temporary shock produces an irreversible rise of the digital markets. This happens for three distinct reasons. First, by temporarily eliminating the physical market, Covid-19 provides a strong incentive for rms to carry out the xed investments necessary to venture into the digital market (supply channel). Secondly, by forcing even the most reluctant consumers into the digital market, Covid-19 pushes them to familiarize with digital platforms, and this con dence endures in the post-Covid era (demand channel). Finally, if consumerstaste for digitalization is a¤ected by the size of the digital market, a market may be entrapped into a low-digital equilibrium inde nitely. In such context, the lockdown due to the pandemic is the shock that may unleash the forces of digitalization and tilt the entire sector towards a high-digital equilibrium (network externalities channel)File | Dimensione | Formato | |
